Phys.org / These blazing blue explosions may be born when a compact dead star slams into a Wolf-Rayet star
Luminous fast blue optical transients (LFBOTs) are among the universe's brightest and fastest explosions but their origin is not completely understood. A new study takes a closer look at the galaxies they occur in, offering ...
Phys.org / America's sewage and manure hold a $5.7 billion key to breaking synthetic fertilizer dependence
Nutrients recovered from animal and human waste could drastically reduce synthetic fertilizer use in the U.S., according to a new Cornell University study that takes into account real-world implementation challenges like ...
Phys.org / Looking deep inside quarks: CMS test probes to 10⁻²⁰ meters and finds no inner structure
According to our current understanding of the universe, quarks are fundamental, point-like particles: basic building blocks that are not made up of smaller particles. A recent paper from the CMS Collaboration describes how ...
Medical Xpress / Cardiorespiratory fitness may cut dementia, depression and psychosis risk
Many studies carried out over the past decades have explored the relationship between mental and physical health, showing that the two are often interlinked. One well-established indicator of overall physical health is cardiorespiratory ...
Phys.org / Mental math's shortcut—pupil dilation suggests people start solving before all numbers are in
People often solve simple arithmetic problems, such as basic addition, subtraction, multiplication or division, in their minds. The precise mental processes they rely on to solve these problems, however, are not entirely ...
Phys.org / Dark matter could explain the earliest supermassive black holes
A growing mystery in astronomy is the presence of gargantuan black holes—some weighing as much as a billion suns—existing less than a billion years after the Big Bang. According to the standard theory of black hole formation, ...
Phys.org / Are aliens real? Scientists have been hunting for extraterrestrial life since the time of Aristotle
Do aliens exist? Could Earth really be the only planet hosting intelligent life?
Medical Xpress / Robust flu protection may rely on B cells that are long-lived residents in the lungs
Deep in the lungs, resident memory B cells stand guard against influenza reinfection—but whether they remain there may depend on how strongly they are signaled through their own receptors. New research using an animal model ...
Phys.org / Hollow-sphere catalyst enables greener production of 99% pure propene at room temperature
The world's appetite for propene (propylene) is growing faster than the chemical industry can keep up. This petrochemical product powers the production of acrylonitrile, propylene oxide, high-velocity fuels, and, most importantly, ...
Medical Xpress / Within primary breast tumors, a high-risk cell state may seed future metastases
Understanding which cells within a tumor will go on to form metastases remains one of the major challenges in cancer research. A study led by the Cell Plasticity in Development and Disease laboratory, headed by Ángela Nieto ...
Phys.org / Surprising link between metallicity and superconductivity uncovered in twisted trilayer graphene
Superconductivity is a state of matter characterized by an electrical resistance of zero, typically at very low temperatures. Past studies have found that in various materials, this unique state is accompanied by unusual ...
Phys.org / Quantum model explains how single electrons cause damage inside silicon chips
Researchers in the UC Santa Barbara Materials Department have uncovered the elusive quantum mechanism by which energetic electrons break chemical bonds inside microelectronic devices—a detrimental process that slowly degrades ...
